The BK mini is the way you will want to go. You cant say how the other alpha cones are going to perform because they are not out yet. With that type of money being invested I would want to go with a sure thing. The BK mini's are anything but mini skimmers. They are built like a tank and have to be about one of the easiest skimmers to clean on the market. From my experience if your budget allows the bk mini gen 2 180, then that is the way I would go. No doubt in my mind about that one.
